1 INTRODUCTION
This instruction describes troubleshooting guidelines for KONE Monospace®2.1 elevators which have
been set-up according to the relevant AM-instructions. The instruction was made using software
versions LCE™: 6.5.9 and drive: 0.75 to analyse the fault behaviour.
1.1 How to use this instruction
This instruction is written using tables to guide the reader through the troubleshooting process. First, a
table with a complete list of points to check is presented. The details of every check are described in
subtables found as appendices. An experienced technician can do troubleshooting using just the top-
level table until the fault is located. The details on how to resolve the fault can then be found in the
subtables.
Read the subtables advancing downwards in the Check-column. Each cell in the Check-column
contains a check, test or a measurement in form of a question. The answer to the question can be YES
or NO. If the answer to the question is
• NO: The reader should continue downwards to the next cell in the Check-column.
• YES: The reader should continue to the right in the same line, where possible cause is explained
and a corrective action suggested. If the fault is not solved after the corrective action, the reader
should continue downwards to the next cell in the Check-column.

If the safety harness is used incorrectly you
may still sustain severe injury or death
during a fall or uncontrolled movement of
the elevator.
If you have attached the harness to a guide rail
bracket or other fixed point in the lift well, you
must ensure that there can be no unwanted
movement of the car or counterweight.
Handle and dispose of waste materials in
accordance with the regulations applicable to
your country/state.
Ensure that your work does not cause a hazard
to others. In particular keep access ways and fire exits clear.
Refer to AS-01.01.004 Take Care End user

3.2 Personal safety
Gloves, safety shoes, helmets, goggles, dust masks, ear defenders and harnesses are provided for
your personal protection. USE THEM AS REQUIRED.
3.3 Maintenance method safety
Note the following safety items when working with elevator electrification:
• General KONE safety regulations and local safety regulations must be followed during the work. All
normal safety measures required in elevator maintenance must be implemented.
• Refer to AM-01.03.002 “Take 5 Electrical Safety When Working on the Elevators”. The Take 5
safety initiative is designed for installation, servicing, maintenance and modernisation work done
on elevators.
• Control panel door must be closed always when not working with panel, even if the main power has
been switched OFF.
• Power must be turned OFF for 5 min. before removing protection shields.
• Ensure that the tools you use (for example multimeter) are in proper condition before and after the
maintenance.
• Ensure that all electrical parts are safely de-energized using proper voltage tester before starting
actual work.
• Safety must be ensured with fences or additional guarding depending on site conditions if
protection shields are removed and main power is ON.
• Arrange temporary protection if it is not possible to switch off adjacent elevators and they are not
already guarded.
• Make sure that the high voltage parts do not cause danger to outsiders. Use additional fences or
guarding, when there is a danger that outsiders enter working zone or there are parts or tools
causing risks of tripping on the landing.
• Do not move the elevator car manually when somebody is working with drive system. Danger of
electric shock even the mains supply is off. (Self excitation voltage of MX-machineries)
• Before making or removing electrical connections for measurements, make sure that the main
power is off and all electrical parts are safely de-energized.

WARNING
Inverter drives usually remain energised for about 5 minutes after the power has
been disconnected.
DO NOT work on the drive, hoisting motor or braking resistors until you have
verified that this energy has been discharged.
Test equipment must be set to the 1000 V DC range. The test equipment must
be checked before and after the test to ensure that it functions correctly.

4 TROUBLESHOOTING PROCESS
4.1 Introduction to troubleshooting
Generally, in a troubleshooting process it is recommended that fast and easy checks are done first.
More specifically, the troubleshooting should always begin in the machine room or at the Maintenance
Access Panel. This thumb-rule is valid even though landing doors and car doors usually have the
highest failure rates in an elevator. After fast and easy checks, the troubleshooting should continue
testing parts, which are cheap to try (for example fuses).
The topic of this instruction is somewhat more complicated and we suppose that before the
troubleshooter has to resort to this document, she or he or perhaps another technician has already
made the first checks without success. The troubleshooting rules that apply generally can not always
be followed in advanced troubleshooting: some checks are quite complicated to do and expensive
replacement parts or even modules might be needed in order to locate the fault. In any case, the
reader should always keep the basic troubleshooting rules in mind. For example, the first option should
not be replacement of boards or other sensitive components which may be damaged in the process -
the fault may still be located somewhere else, for example in the cable connection.
4.2 Safety measures
The following safety measures must be carried out before beginning the actual work:
Step Action Illustration/Note
1 Ensure that no one is in the elevator car.
2 Ensure that no one is doing any
maintenance work on the same elevator.
3 Ensure that the troubleshooting can be
done safely and there is no immediate
danger of further damages for the elevator
(for example counterweight or car off the
guide rails).
4 Always follow KONE safety instructions
described in AM-01.03.002 and local safety
regulations for electrical work.
5 Before checking any unprotected
equipment, making any connections for
measurements or removing them, ensure
that doing it is safe.
If necessary, ensure that the power is
switched off and the equipment is de-
energized.

The following safety measures must be carried out when the work is completed:
4.3 Basic rules preventing ESD hazards (Electrostatic discharge)
Follow the procedures and use the tools described in AS-12.02.001 Instruction for handling ESD
sensitive devices.
1 Earth yourself before touching components, use a wrist strap combined with
a portable ESD working pad.
2 Disconnect all power supplies
3 Do not unpack the spare parts before installation.
4 Do not touch the components on the board unnecessarily.
5 Hold the PC-board from its edges do not touch the connectors.
6 The old component must be handled in the same way as the new one.
7 Use ESD- working pad to lay the components down. (Insulation material
does not protect against ESD damage).
8 Do not wear combinations of clothing that can create static charges.
4.4 Tools
• Fluke 197 Multimeter (or similar) with suitable wires and probes for measurements
• ESD kit, KM857505
• Standard maintenance tools
• Spare fuses: 250V, 1A; 250V, 2A; 250V, 6.3A; 400V, 2...6A
NOTE! Always make sure that you replace blown fuse with a similar new fuse. Different board
versions may have different types of fuses.
Step Action Illustration/Note
1 Remove all temporary overconnections that
were made during the maintenance.
2 Ensure that the elevator is left in safe
condition for building users. NOTE! If the elevator can not be left in safe
condition, it must be taken out of service.
Follow the local requirements.
3 Inform the customer about the work done on
the elevator and the condition it is after your
maintenance (in service / out of service).
4 Fill the internal reports/log books.

Cause unknown, the
elevator seems to be
working correctly now.
No actions. Follow-up the
elevator operation for a
while.
2 Main switch 220 goes OFF
again, after it has been
turned ON?
Proceed to Step 2a.
aTurn powerOFF, unplug XS3 connector from V3F16L and
measure the resistance from
drive module/XS3 pin 1 to 3
(start permit chain).
Resistance is over 1MOhm?
Drive is defective if the
resistance is over 1MOhm
(resistance between 0.5
and 1MOhm is ok).
Replace the defective
V3F16L.
bPlug in XS3 and then unplug LCEREC/X1 and turn the
main switch 220 ON.
Does it stay ON?
Short circuit in LCEREC. Replace the defective
LCEREC.
cThe main switch 220 goes OFF again. Short circuit in the supply cables or in the V3F16L. Fix the cables. If it does not help, replace the
defective V3F16L.

2 F2 fuse seems to be OK but
blows when the elevator tries
to run?
Proceed to Step 2a.
aCheck the brakes and the wiring:
Unplug XBR3 and measure
the resistance of the brake
coils between pin 1 and 3,
and between 2 and 3.
Typical values for brake coil
resistance are
- for MX5 and MX6:
320 Ohm (+/-20 Ohm),
- for MX10:
220 Ohm (+/-20 Ohm).
Is the measured resistance
below the typical value? Short circuit in the brake
coil. Replace the defective brake module.
bF2 fuse blows when the elevator tries to run and the
brake coil resistance
indicates that the brakecoil is
OK.
Brake power circuit failure
on V3F16L. Replace the defective V3F16L.
